Extensive Farming
Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labour, fertilizers, and capital, relative to the land area being farmed. Systems Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia. Here, owing to the extreme age and poverty of the soils, yields per hectare are very low, but the flat terrain and very large farm sizes mean yields per unit of labour are high. Nomadic herding is an extreme example of extensive farming, where herders move their animals to use feed from occasional rainfalls. Geography Extensive farming is found in the mid-latitude sections of most continents, as well as in desert regions where water for cropping is not available. The nature of extensive farming means it requires ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methane Emissions
Increasing methane emissions are a major contributor to the rising concentration of greenhouse gases in Earth's atmosphere, and are responsible for up to one-third of near-term global heating. During 2019, about 60% (360 million tons) of methane released globally was from human activities, while natural sources contributed about 40% (230 million tons). Reducing methane emissions by capturing and utilizing the gas can produce simultaneous environmental and economic benefits. Since the Industrial Revolution, concentrations of Atmospheric methane, methane in the atmosphere have more than doubled, and about 20 percent of the warming the planet has experienced can be attributed to the gas. About one-third (33%) of anthropogenic greenhouse gases, anthropogenic emissions are from gas release during the mining, extraction and delivery of fossil fuels; mostly due to gas venting and gas leaks from both active fossil fuel infrastructure and orphan wells. Russia is the world's top methane e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

African Oil Palm
''Elaeis guineensis'' is a species of palm commonly just called oil palm but also sometimes African oil palm or macaw-fat. The first Western person to describe it and bring back seeds was the French naturalist Michel Adanson. Jean-Marie Pelt, « Michel Adanson, le baobab et les coquillages », dans ''La Cannelle et le panda : les grands naturalistes explorateurs autour du Monde'', Fayard, 1999 . It is native to west and southwest Africa, specifically the area between Angola and The Gambia; the species name, ''guineensis'', refers to the name for the area called Guinea, and not the modern country Guinea now bearing that name. The species is also now naturalised in Madagascar, Sri Lanka, Malaysia, Indonesia, Central America, Cambodia, the West Indies, and several islands in the Indian and Pacific Oceans. The closely related American oil palm '' E. oleifera'' and a more distantly related palm, '' Attalea maripa'', are also used to produce palm oil. ''E. guineensis'' was dom ...

Black Iberian Pig
The Iberian pig, also known in Portugal as the Alentejo Pig, is a traditional breed of the domestic pig (''Sus scrofa domesticus'') that is native to the Iberian Peninsula. The Iberian pig, whose origins can probably be traced back to the Neolithic, when animal domestication started, is currently found in herds clustered in Spain and the central and southern part of Portugal. The most commonly accepted theory is that the pigs were first brought to the Iberian Peninsula by the Phoenicians from the Eastern Mediterranean coast (current-day Lebanon), where they interbred with wild boars. This cross gave rise to the ancestors of what are today Iberian pigs. The production of Iberian pig is deeply rooted to the Mediterranean ecosystem. It is a rare example in world swine production where the pig contributes so decisively to the preservation of the ecosystem. The Iberian breed is currently one of the few examples of a domesticated breed which has adapted to a pastoral setting where t ...

Cork Oak
''Quercus suber'', commonly called the cork oak, is a medium-sized, evergreen oak tree in the section Quercus sect. Cerris, ''Quercus'' sect. ''Cerris''. It is the primary source of cork (material), cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls. It is native to southwest Europe and northwest Africa. In the Mediterranean basin the tree is an ancient species with fossil remnants dating back to the Tertiary period. It can survive for as long as two centuries. Typically, once it reaches 25 years old, its thick bark can be harvested for cork every 9 to 12 years without causing harm to the tree. It endures drought and makes little demand on the soil quality and is regarded as a defence against desertification. Cork oak woodlands are home to a multitude of animal and plant species. Since cork for sealing bottles is increasingly being displaced by other materials, these forests are at risk as part of the cultural landscape and as a ...

Montado
A ''dehesa'' () is a multifunctional, agrosylvopastoral system (a type of agroforestry) and cultural landscape of southern and central Spain and southern Portugal; in Portugal, it is known as a ''montado''. Its name comes from the Latin ''defensa'' (fenced), referring to land that was fenced and usually destined for pasture. Dehesas may be private or communal property (usually belonging to the municipality). Used primarily for grazing, they produce a variety of products, including non-timber forest products such as wild game, mushrooms, honey, cork, and firewood. They are also used to raise the Spanish fighting bull and the source of jamón ibérico, the Iberian pig. The main tree component is oaks, usually holm ('' Quercus rotundifolia'') and cork (''Quercus suber''). Other oaks, including melojo ('' Quercus pyrenaica'') and quejigo ('' Quercus faginea''), may be used to form dehesa, the species utilized depending on geographical location and elevation. Dehesa is an anthropog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
